Methods in Plant Histology. By Chas. J. Chamberlain, Pli. D. 160pp. 



octavo, illustrated, cloth. University of Chicago Press, 1901, $1.50. 



The work which has just appeared under the above title is based 

 upon a series of articles which have already been published in the Jour- 

 nal of Applied 3Iicroscopy. The articles, however, have been thoroughly 

 revised and enlarged, so that the present book contains about twice the 

 matter of the original articles. The subject is treated in two parts, 

 Part I. containing chapters on apparatus, re-agents, temporary mounts, 

 the general method, killing and fixing agents, staining, general remarks 

 on staining, practical hints on staining, the celloidin method and the 

 glycerine method. Part II. describes the special methods of technique 

 to be applied in studying the different groups of plants, beginning with 

 the algae. Fungi, hepatics, mosses, ferns, horsetails, lycopods, gymno- 

 sperms, and angiosperms are taken up in their regular order, and sim- 

 ple and comprehensive directions for the preparation and study of 

 members of the various groups are given. The final chapters are de- 

 voted to " a class list of preparations " adapted to meet the needs of a 

 regular course in plant histology, and formulae for reagents in which 

 are brought together the various fixing agents and stains in general use. 

 The work is evidently intended to meet the needs of general students 

 in plant histology, and is based upon the outhor's own work with his 

 classes at the University of Chicago. While it is not so complete in 

 some ways as Zimmerman's work, yet it seems much better adapted to 

 the use of general students. The matter is well arranged and illus- 

 trated. The second part of the book, though rather brief in its treat- 

 ment of some groups, will, we believe, prove very useful to all teachers 

 of plant histology. The book will no doubt find a place in every well 

 regulated laboratory, and will be found very useful by private students.
